Playdough

I know this is technically not edible, but I know a lot of you have kids and kids + playdough = awesome fun. I make playdough at least once a month for my class at school and I really like this recipe. Very similar texture to real "playdough". A tad bit more salty though. One recipe makes 1 of the bowls seen below.
Ingredients:
1 c. flour
1 c. water
1/2 c. salt
1 T. cream of tarter

Mix all ingredients in a pot. Cook on medium heat, stirring until the dough starts to pull apart from sides and form a ball. Let cool, then put in an air tight container.

*This dough will last for a very long time if put away in a sealed container right after it is used. I once had some that lasted for 6 months.
